<description>
|
|
A material that uses a custom [Shader] program to render either items to screen or process particles. You can create multiple materials for the same shader but configure different values for the uniforms defined in the shader.

Changes the value set for this material of a uniform in the shader.
|
|
[b]Note:[/b] [param param] is case-sensitive and must match the name of the uniform in the code exactly (not the capitalized name in the inspector).
|
|
[b]Note:[/b] Changes to the shader uniform will be effective on all instances using this [ShaderMaterial]. To prevent this, use per-instance uniforms with [method GeometryInstance3D.set_instance_shader_parameter] or duplicate the [ShaderMaterial] resource using [method Resource.duplicate]. Per-instance uniforms allow for better shader reuse and are therefore faster, so they should be preferred over duplicating the [ShaderMaterial] when possible.
